The British Library's new Listen to Nature web site features 400 recordings selected from the more than 150,000 animal sounds held by the Library. Listen to Nature can be browsed by location, animal type, or habitat. Maps are provided with red dots plotting the locations of recordings; clicking any dot launches a player and the sound file. Alphabetical lists of animal sounds also accompany maps from the region. Visitors are invited to search the Catalogue, in this case the combined catalogue of the British Library Sound Archive, which includes all types of recorded sound. It is best to use the advanced search, limit searches to Wildlife sounds, and look for the "Electronic access" link. On a recent visit we heard loons, wolves, and a whip-poor-will recorded in Canada, enjoying the ability to hear sounds originally captured in North America sent back to us from the UK via the Internet.
